To fully demonstrate the superiority of ADC, we perform ablation studies on different models, including the family of SimpleBaseline [1]} and HRNet [2]}. The results are shown in Table REF . As one can see, ADC can bring consistent improvement for different models. For the smallest model, i.e. SimpleBaseline-Res50, ADC brings an improvement of \(1.4\)  on \(AP\)  score. For the largest model, i.e. HRNet-W48, there is still an improvement of \(0.4\)  on \(AP\)  score. The increments decay as the \(AP\)  scores increase. This may because it is harder to improve the performance of a more accurate model. From \(AP^{M}\)  and \(AP^{L}\) , we can see that the improvements in medium and large persons are roughly the same. It indicates that ADC benefits equally the keypoint detection of large and medium persons.
